In some cases, it is required to pass a value to ActionListener of ADF Button.
The method that can be invoked by actionListeners has only one parameter of type ActionEvent.
So I will explain how to pass parameter to that bean method however it contains only one paramater ActionEvent in method signature.
I added button to my page as below
The default signature of ActionLister is
The workaround I used is adding an attribute tag from the JSF.Core inside the ADF Button So the code in the jsp page looks like this
Note “MyAttrName” is the name of paramater and “MyAttrValue” is the value of paramater.
You can bind “MyAttrValue” to get any value from page definition.
Now I will write the followign code to get paramatervalue from bean
The variable “attrValue” holds the value of paramaters which is “MyAttrValue” in this example.
Thanks
